Here's a collection of vero and tagboard guitar and bass effect layouts that we have put together covering all of the classic and popular effects in ever growing numbers. Many of these have been posted on two excellent forums, freestompboxes.org and circuitworkshop.com. Check those out for other great designs, layouts and discussions on building your own effect pedals. Enjoy the builds and please visit us at www.facebook.com/tagboardeffects!
There was a bit hassle with this one, but now it's verified and working. Comments on the post are a good read if you're building this. Thanks to Mr. Photon for his amazing work, and special thanks to Pete who verified this.
Mind the notes about the transistors. This is drawn from schematic marked as revision G (The Maestro of Rock version).
